Overview

Knowledge graph embedding (KGE) is a method for representing symbolic facts in low-dimensional vector spaces, with the goal of projecting relations and entities into a continuous vector space. This approach enhances knowledge reasoning capabilities and facilitates application to downstream tasks.

We introduce DeltaKG (MIT License), a dynamic, PLM-based library for KGEs that equips with numerous baseline models, such as K-Adapter, CaliNet, KnowledgeEditor, MEND, and KGEditor, and supports a variety of datasets, including E-FB15k237, A-FB15k237, E-WN18RR, and A-WN18RR.

DeltaKG is now publicly open-sourced, with a demo, a leaderboard and long-term maintenance.

Installation

Step1 Download the basic code

git clone --depth 1 https://github.com/zjunlp/PromptKG.git

Step2 Create a virtual environment using Anaconda and enter it

conda create -n deltakg python=3.8
conda activate deltakg

Step3 Enter the task directory and install library

cd PromptKG/deltaKG
pip install -r requirements.txt

Data & Checkpoints Download

Data

The datasets that we used in our experiments are as follows,

• E-FB15k237

  This dataset is based on FB15k237 and a pre-trained language-model-based KGE. You can download the E-FB15k237 dataset from Google Drive.

For other datasets A-FB15k237, E-WN18RR, and A-WN18RR, you can also download from the above link.

Checkpoints

The checkpoints that we used in our experiments are as follows,

• PT_KGE_E-FB15k237

  This checkpoint is based on FB15k237 and a pre-trained language model. You can download the PT_KGE_E-FB15k237 checkpoint from Google Drive.

For other checkpoints PT_KGE_A-FB15k237, PT_KGE_E-WN18RR, and PT_KGE_A-WN18RR, you can also download from the above link.

How to run

• script

  • The script run.sh has three arguments -m, -d, and -t, which stand for model, dataset, and task.
    • -m: should be the name of a model in models (e.g. KGEditor, MEND, KE);
    • -d: should be either FB15k237 or WN18RR;
    • -t: should be either edit or add.

• Edit Task

  • To train the KGEditor model in the paper on the dataset E-FB15k237, run the command below.

        bash run.sh -m KGEditor -d FB15k237 -t edit
    

  • To train the KGEditor model in the paper on the dataset E-WN18RR, run the command below.

        bash run.sh -m KGEditor -d WN18RR -t edit
    

• Add Task

  • To train the KGEditor model in the paper on the dataset A-FB15k237, run the command below.

        bash run.sh -m KGEditor -d FB15k237 -t add
    

  • To train the KGEditor model in the paper on the dataset A-WN18RR, run the command below.

        bash run.sh -m KGEditor -d WN18RR -t add
